Summary and Future Directions •  Tremendous opportunity in control technology to improve

building performance •  Continuously measure and report performance •  Low-cost, embedded systems enable new capabilities •  Continued need for greater interoperability – less vendor lock in •  Continue to evaluate user experience, aggregation models,

robustness and user friendliness / behavior agenda
